Abstract
Description
Condition | The immediate data file command that is produced |
The beginning of LBA order | Write _ pointer this order of < file ID>< side-play amount>offset address in the current file is set, next write command will be in this place, address operation. |
Current file is not opened and is opened _ file=maximum | Guan Bi<Wen JianID>+ idle+time-out<Up to _ or not busy>This order group closes the file of access least recently, and impels device to carry out all garbage collection operations to file co-pending. |
Current file is not opened | Da Kai<Wen JianID>+ write _ Zhi Zhen<Wen JianID><Pian Yiliang>This order group opens current file, and offset address is set, and next write command will be worked at this place. |
Current file changes | Xie Ru<Wen JianID>+ flow+write _ Zhi Zhen<Wen JianID><Pian Yiliang>This order group writes the data of the last file of accumulation, and the offset address in the current file is set, and next write command will be in this place's operation. |
Program area block is full | Xie Ru<Wen JianID>This order group of+stream writes the data of the current file of accumulation. |
Program area block has been expired and effective _ page or leaf>Minimum value | Guan Bi<Wen JianID>+ idle+time-out<Up to _ or not busy>This order group closes current file, and impels device to carry out all garbage collection operations to file co-pending. |
The end of LBA order | Xie Ru<Wen JianID>+ stream+preservation _ buffering<Wen JianID>This order group writes the data of the current file of accumulation, and impels the not programming data that is retained in the impact damper to be programmed into " exchange block " in the flash memory. |
Order | Parameter | Describe |
